Sunday, San Diego (0-1) will play the Eagles (1-0) at 1 p.m. on Lincoln Financial Field. Here’s five things you should know for the game...

1. THE PACE
Usually you talk about pace in a horse race, and what horses will set it, chase it or try to close into it.

With the Eagles new offense, it’s about the defense trying to keep pace as Chip Kelly calls play after play in record-setting time. But keep in mind the Eagles ran 31 plays in the first quarter last week, 53 in the first half, but just 77 for the game. So they ran fewer plays in the second half (24 for those of you not good in math) than they did in the first quarter.

Some of that was Kelly taking his foot off the gas, or was it his team was gassed? We’ll find out more this week.

2. ROLLING ON THE RIVERS
The Eagles defense will try to get pressure on San Diego quarterback Phillip Rivers and forced him into turnovers. There are two interesting tackles in front of the Chargers’ veteran QB.

On the right side is rookie D.J. Fluker, the team’s first-round pick out of Alabama where he was coached by current Eagles offensive line coach Jeff Stoutland.

On the left side is former Eagle, King Dunlap, who struggled for the most part in his time with the team.

Look for Trent Cole, who played well a week ago in Washington, to have a big game.

3. LEFT OR RIGHT
San Diego’s best pass rusher is former Colt Dwight Freeney who signed as a free agent this year.

Freeney generally lines up on the right side of the defense, which means he goes against the left tackle. In that case it would be against the Eagles All Pro Jason Peters.
Word is this week, Freeney has taken snaps on the left side, which means he may go against Eagles first-round draft pick Lane Johnson more than usual.

Johnson did OK in his debut last week. He had some trouble with Washington’s Ryan Kerrigan at times and was called for a flase start penalty.

4. DOES SIZE MATTER?
With cornerback Bradley Fletcher (concussion) out for the Eagles, nickel corner Brandon Boykin is expected to see more time outside. Boykin is listed as a generous 5-foot-10 on the roster. He’s closer to 5-9, or maybe 5-8.

It will be interesting to see if the Chargers try to get him matched up against wide receiver Malcolm Floyd, who stands 6-5. Floyd caught just one pass for 47 yards last week against Houston, but an eight-inch height advantage may be too much to resist.

5. DOUBLE WHAMMY
The NFL did not do the Chargers any favors. One of my favorite trends is when a West Coast team comes East and plays a 1 o’clock game, take the home team.

Another is when a team plays Monday night and has to travel the following week, take the home team. San Diego has to do both this week.
